[Linux-cluster] RH Cluster issue-Network Failover not happening

Issue: When network cable is disconnected from the Primary, primary restart
unclean and the failover to secondary do not happens. The shared drives
don't get mounted automatically for secondary neither gets it mounted on
primary, after the primary restarts. I have to then manually shut down both
Primary and Secondary, and start primary first and then secondary for the
setup to work fine again.

I want to test a live production setup... a Linux Cluster with 2 nodes, in
Linux Advanced Server (Linux DB-Primary 2.4.21-37.ELsmp #1 SMP Wed Sep 7
13:28:55 EDT 2005 i686 i686 i386 GNU/Linux ), Oracle data base is running on
this setup.

The clumanager version is 1.2.28 and redhat-config-cluster version is 1.0.8
on both primary and secondary.I want to resolve the issue with out any
upgradations. Do you think that updating can resolve the issue? If
upgradation is required please guide how to go ahead. I am trying to resolve
this issue with out any patch update.
Is this a configuration problem or some knows issue with the version used.

Cluster.xml looks like this.

  <?xml version="1.0" ?>
